Abstract: ABSTRACT     Aldoses  such  as  glucose  solution  are  catalytically hydrogenated in a multiple-stage fixed-bed reaction process to  produce  glycerol  and  other  polyol  products.     The feedstream pH to each reactor is controlled to between about 7 and  14 by adding an alkaline promoter  material such as calcium hydroxide.   First-stage reaction zone conditions are 130-180°C   temperature,   500-2000   psig   hydrogen   partial pressure,  and  feedstream  liquid  space  velocity  is  within. range of 0.5-3.5 Vf/Hr/Vc.   The first reactor uses a high activity nickel  catalyst to produce at least about 98 W % conversion to alditol such as sorbitol solution.     The resulting alditols such as 15-40 W % sorbitol solu-tion in water are catalytically hydrocracked in a second-stage fixed-bed  reaction  zone  preferably  using  a  high-activity nickel catalyst to produce at least about 30 W % conversion to glycerol and glycols products.  Second-stage reaction zone conditions are 420-520°F temperature, 1200-2000 psig hydrogen partial pressure, and liquid hourly space velocity of 1.5 to 3Ø  The reaction products are separated in a recovery step, and  unconverted  heavy  alditol  feed  can  be  diluted  and recycled  to  the  second-stage  reaction  zone  for  further hydrogenolysis  to  produce  40-90  W %  glycerol  product.          Sorbitol conversion is maintained preferably at between about 30-70 W % and a purge stream containing unconverted sugars is passed to a third-stage catalytic reaction zone for further conversion to alditols and polyols.

Abstract: PRINTED WIRING BOARD SUBSTRATES                FOR CERAMIC CHIP CARRIERS                        ABSTRACT A composite printed wiring board is provided wherein the surface of the board is fabricated from conventional fiber reinforced plastic laminates such as glass fiber reinforced epoxy laminates and that laminate is secured by means of a thermoset adhesive to a support member which is fabricated from graphite filament reinforced  thermoset resin having a low coefficient of thermal expansion approaching zero.  The unrestrained coefficient of thermal expansion of the printed wiring board is significantly greater than that of the support member.  However, in the composite assembly, the apparent co-efficient of thermal expansion of the printed wiring board is greatly reduced and can approximate the coefficient of thermal expansion of a ceramic chip carrier.  The coefficient of thermal expansion of the printed wiring board in its thickness direction is only slightly reduced in the composite assembly.

Abstract: ABSTRACT OF THE DISCLOSURE         A strip of heated thermoplastic material is extruded from a die past first and second stations while the strip is drawn down between the die and the first station.  Initial cooling of the strip is performed at the first station and further drawing down of the strip is effected between the first and second stations.  The strip is thereafter guided through a plurality of spaced convolutions about a journaled cylindrical member driven at a peripheral speed substantially equal to the linear speed of the strip as it enters the second station.  Substantial full cooling of the spiral strip is performed at the second station by a bath of cooling liquid through which the strip is linearly advanced and the strip is subsequently driven, at a linear speed substantially equal to the peripheral speed of the cylindrical member, from the second station into a third station in which the coiled strip is cradled between parallel rollers driven at peripheral speeds substantially equal to the linear advancing speed of the coiled strip.  The cradled strip is subsequently annealed during its movement through the third station by both internal and external sprays of heated liquid thereon.

Abstract: A two-directional percussion implement selectively adaptable both for driving in and for extracting, e.g. piles, from the ground, includes two coaxial electromagnetic coils whose movable armatures are represented by extremities of a reciprocable ram. Opposite anvils, one of which is adapted to be coupled with a driven element, are interlinked by a non-magnetic shaft traversing the ram. When the implement is intended for drilling operations, a rotary drive imparts rotation to one of the anvils via a connection permitting independent rotation and reciprocation. The shaft in this case has a central channel for taking samples or for conducting drilling fluids. When adapted only for axial percussions, the implement is vertically suspended on a cable via a shock absorber.

Abstract: ABSTRACT OF THE DISCLOSURE An adjustable stablising device which is attached to an extension ladder without requiring modification of the ladder structure or affecting normal operation of the ladder is described.  The device has two stabilising elements made of aluminum which are located at different side of the ladder. Each stabilising element has an upper and a lower bracket which are connected together by two rigid pivotably-linked longitudinal members.  The stabilising elements are connected to each other by rods which extend through the rungs of the ladder and which connect the upper and the lower brackets.  The lower bracket and the lower longitudinal member are pivotably connected, and the upper bracket has a number of apertures spaced lengthwise of the ladder.  By choosing the aperture to which the upper longitudinal member is connected, the attitude of each of the lower members is varied via the pivotable connection so as to conform to the surface adjacent the ladder side.  When not in use, the stabilising elements are retained flush against the sides of the ladder for storage.

Abstract: ABSTRACT A novel three-dimensional radiation fringe velocimeter subsystem and a subsystem for determining air density related parameters, are combined into a single optical system which permits various important parameters associated with the operation of an aircraft to be measured at a sample location at a sufficient distance from the aircraft (or any physical attachment thereto) so that the measurements will not be subject to systemic errors such as those caused by air compression effects and airflow disturbances, and which does not require that any Pitot tubes, pressure ports or other similar mechanical devices protrude into the airstream where the measurements are to be made.  The combined system contains a laser or other suitable source of radiation as well as an optical arrangement for transmitting the radiation from the laser to a sample volume in order both to form linearly independent sets of radiation fringes at the sample location as well as to  focus the radiation at the sample location so as to cause selected air molecules to fluoresce.  The device also contains an optical receiving arrangement for focusing backscattered radiation and fluorescent emissions from the sample volume onto one or more photodetectors.  By using a radiation source (such as a Q-switched laser) that can be quickly switched between an On state and Off state, it is possible to utilize a single photo-detector, since the backscattered radiation will cease as soon as the radiation is turned off, but the fluorescent emissions will decay exponentially.

Abstract: DRIPLESS CANDLE Abstract Of The Present Invention A non-drip candle is formed of three layers including a thick low melt point core and a thick outer confining high melt wax layer affixed to the core by a special inter-mediate layer.  The intermediate layer formulation includes a paraffin candle wax in combination with a similar quantity of double pressed stearic acid and a high purity tallow acid in the range of 15 to 60% and preferably 5 to 10% by weight. A microcrystalline wax of about 5% increases the melt point and produces a smooth finish to the candle, and a resin of about 1.% imparts hardness to the layer to permit processing. The candle burns with a shallow rim confining the wax pool about the wick and the multiple layer construction function to practically instantaneously heal any breach in the rim as the result of deflection of the flame or physical engagement with the rim to establish a true drip-less candle.

Abstract: SYSTEM FOR DETECTING AND CORRECTING        CONTEXTUAL ERRORS IN A TEXT PROCESSING SYSTEM                          Abstract A system for automatically proofreading a document for word use validation in a text processing system is provided by coupling a specialized dictionary of sets of homophones and confusable words to sets of di-gram and N-gram conditions whereby proper usage of the words can be statistically determined.  A text document is reviewed word-by-word against a dictionary of homophones and confusable words.  When a match occurs, the related list of syntactic rules is examined relative to the context of the subject homophone or confusable word.  If the syntax in the immediate context of the homophone or confusable word conflicts with the prestored syntax rules, the homophone or confusable word is highlighted on the system display.  The system then displays the definition of the highlighted word along with possible intended alternative forms and their respective definitions.  The operator can examine the word used and the possible alternatives and make a determination as to whether an error has been made and if a correction of the text is required. If correction is required, the operator may cause the error word to be replaced by the desired word by positioning the display cursor under the desired word and depressing an appropriate key on the system keyboard.
